TECHNICAL FIELD

The present invention relates to a novel carboxylic acid compound useful for prevention or treatment of hyperglycemia and hyperlipemia, a salt thereof, an ester thereof or a hydrate of them, and to a medicament comprising the compound.

PRIOR ART

Diabetes mellitus refers to a durable hyperglycemic condition attributable to the absolute or relative shortage of intrinsic insulin (blood sugar-depressing hormone produced and secreted from Langerhans islet β cells in the pancreas), and in this disease, metabolic abnormalities caused by this condition appear as various morbid states.

Diabetes mellitus is classified roughly into insulin dependent diabetes mellitus (IDDM) that is diabetes mellitus of first type, for treatment of which insulin administration is absolutely necessary, non insulin dependent diabetes mellitus (NIDDM) that is diabetes mellitus of second type, and other diabetes mellitus (secondary diabetes mellitus; diabetes mellitus occurs as one symptom of other diseases).

In particular, as life-style is modernized, NIDDM is rapidly increased due to overeating and lack of exercise, thus causing a social problem. While IDDM occurs mainly in infants, NIDDM occurs in middle-aged or elderly persons, to account for the majority of diabetes mellitus in Japan. It is said that NIDDM occurs owing to insulin function-suppressing factors (insulin resistance) such as overeating, lack of exercise, obesity and stress in addition to hereditary factors.

Since excessive intake of calories and obesity resulting from lack of exercise are related to diabetes mellitus as described above, the therapy is based on 3 kinds of therapies, that is, dietary therapy, exercise therapy and chemotherapy.

However, there are not a few cases where dietary therapy and exercise therapy are hardly to conduct because of an increase in the number of persons of advanced age in this aging society in recent years.

In chemotherapy of NIDDM, sulfonyl urea (SU) medicines such as tolbutamide, chlorpropamide and tolazamide and biguanide (BG) medicines such as metformin and buformin have been used as oral blood sugar depressants, but the morbid state of NIDDM is characterized by insulin deficiency and insulin resistance, and it cannot be said that the SU medicines stimulating insulin secretion from pancreatic β cells are effective therapeutic medicines for the insulin resistance of NIDDM because the sufficient insulin secretion induced by the medicines cannot be well controlled in a target organ, thus permitting high blood sugar levels. Further, the BG medicines may permit the onset of lactic acid acidosis, so use of such medicines is limited to a certain extent. Further, these chemicals often caused severe low blood sugar as a side effect.

To solve these problems, development of chemicals with a new working mechanism is advancing, and thiazolidine derivatives such as Troglitazone, Pioglitazone and Rosiglitazone are called insulin-resistant improvers, and these chemicals recently attract attention because they can ameliorate insulin resistance (or enhance the action of insulin) and lower blood sugar without promoting secretion of insulin from the pancreas.

It has been revealed that these thiazolidine-type chemicals are related to differentiation of adipocytes, and exhibit their action via an intranuclear receptor PPARγ (peroxisome proliferator-activated receptor gamma: a transcriptional factor important for differentiation of adipocytes) (J. Biol. Chem., 270, 12953-12956, 1995). By the differentiation of pre-adipocytes, immature and small adipocytes with less secretion of TNFα, FFA and leptin are increased thus resulting in amelioration of insulin resistance.

Thiazolidine derivatives such as the above Troglitazone, Pioglitazone and Rosiglitazone also act as agonists for PPARγ, to exhibit the effect of ameliorating insulin resistance.

Besides PPARγ, PPAR subtypes such as α, β etc. have been found, any of which regulate expression of genes involved in lipid metabolism. The homology of each subtype among different biological species is higher than the homology of these subtypes in the same species, and with respect to distribution of each subtype in tissues, PPARγ is located substantially in adipose tissues while PPARα occurs mainly in the liver, heart and kidney, and therefore it was considered that each subtype has an independent function. In recent years, it has been revealed that PPARγ mainly mediates lipid anabolism by promoting expression of a group of genes for LPL, acyl-CoA carboxylase, GPDH etc. to convert sugar into lipid and storing the lipid, while PPARα mediates lipid catabolism by regulating expression of a gene group involved in intake of fatty acids into cells and oxidation thereof to decompose lipid.

As thiazolidine derivatives acting as PPARγ and α dual agonists, compounds disclosed in e.g. JP-A 9-48771 are known.

Further, some compounds are known as insulin-resistant improvers having a carboxylic acid moiety in their structure (Current Pharmaceutical Design, 2, No. 1, pp. 85-102, 1996; Bioorganic & Medicinal Chemistry Letters, 6, No. 17, pp. 2121-2126, 1996).

However, it has been reported that some chemicals acting as PPARγ agonists cause hepatic damage and thus should be carefully used, so chemicals satisfactory in both therapeutic effects and side effects such as toxicity are still not obtained.

Further, compounds having a thiazolidine moiety replaced by a carboxylic acid derivative are merely presented in literatures and not marketed. Further, there is no report showing that such compounds can be used as PPARγ and α dual agonists, and as a matter of course, their γ, α and β triple agonist action is not known. However, it is also estimated that the toxicity of PPARγ agonists described above is the unique one derived from the thiazolidine moiety, and if a compound exhibiting the above action with a new structure in place of the above structure can be found, the compound can be expected to solve the problem of toxicity, and is thus very useful.

The conventional chemicals are still unsatisfactory in respect of neutral fat (triglyceride (TG)) related closely to arteriosclerosis.

Further, the action gf PPARβ to induce differentiation of adipocytes is known (J. Biol. Chem., 274, No. 31, pp. 21920-21925), and by this action, cholesterol levels are reported to be lowered (WO9904815), and if a compound having an agonist action for this subtype can be found, this compound can be expected to exhibit a higher activity than that of the conventional insulin-resistant improvers and to reduce side effects such as hepatic toxicity.

From the foregoing aspects, there is demand for development of excellent chemicals.
